Shared calendar meeting requests from Web App RRS feed

  • Question

  • Hi

    I was wondering if anyone is able to provide some feedback on feasibility of performing CRUD operations on shared calendars from a web app (LAMP architecture).

    The steps I have followed so far in trying to get this to work is:

    - Created an app in Azure with permission to MS Graph, Office 365 Exchange Online shared calendars

    - Updated  "keyCredentials" in the manifest (signed cert)

    I can successfully obtain a token using curl: 

    curl -X POST  -H "Accept: application/json" -H "Content-Type: application/x-www-form-urlencoded" -d 'client_id=my-client-id’ -d 'grant_type=client_credentials' -d 'client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer' -d 'client_assertion=my-assertion’ -d 'resource=https://graph.windows.net' 'https://login.windows.net/my-tenant-ID/oauth2/token'

    This token however errors when I use it to retrieve a test shared-calendar event with the error: token has no permissions

    Any help would be much appreciated.

    thanks,

    Sina
